If the interface is used as an analogue input, the ventilation unit can be integrated into an exist-
LQJKRPHDXWRPDWLRQV\VWHP7RGRVRDSUHGH¿QHGYROWDJHOHYHOLVVHWLQWKHKRPHDXWRPDWLRQ
control unit, depending on the desired function.
TIP:
It is not possible to connect a potential-free switch and an analogue input simultaneously.
A connected analogue input always has priority over a potential-free switching contact.
The jumper on the back of the operating unit must not be attached.
Depending on the control voltage, the following functions are available:

Activating the controller
After activating the controller (e. g. after a power cut), the heat recovery mode will be active.
Requirements:
7KHFRQWUROOHULVVZLWFKHGRႇ
Ö
You have activated the controller.
Ö
You can switch modes and change the output
level.
If no change is made after the controller is activated, the controller will switch on the reversible
fans at the lowest output level after 60 minutes.

The external interface is a bi-functional port on the back of the operating unit. It enables the
connection of a sensor with a potential-free switching contact (NOC) or the use of an analogue
input to integrate the ventilation unit into an existing home automation system.
Connecting the external interface changes the functionality of your controller as follows:
A. Interface as external switching contact
The sensor used must have a potential-free relay contact (NOC). The function settings of the
interface are adjusted via the jumper on the back of the operating unit.

Consult a chimney sweep/construction planner about this. If the interface is used for a pressure
switch, the air pressure in the interior is measured continuously. Once the air pressure exceeds
RUIDOOVEHORZWKHVDIHW\WKUHVKROGWKHVHQVRUUHDFWVDQGWXUQVRႇDOOFRQQHFWHGYHQWLODWLRQ
units.
If the external interface is used to connect a
• CO
2
sensor, the CO
2
content in the interior is measured continuously.
• hygrostat, the relative humidity in the interior is measured continuously.
• VOC sensor, the composition of the air and the resulting air quality are measured continuously.
A CO
2
sensor and a hygrostat are optionally available as accessories.
Once the respective value exceeds the upper limit or falls below the lower limit, the sensor
reacts and switches all connected ventilation units to ventilation mode, output level 4.
